Haptic interaction to realize collision and contact of dental tools in double-channel haptic display system

The construction of dynamic tools interaction for dental training system was introduced. The dental training system is a double-channel haptic interaction system, which enables dentists to practice dental skills in the virtual reality dental training system with both his hands. Therefore, if the tools collide in virtual environment, operators should feel feedback force. The tool for computing and the tool for display were proposed to realize stable and realistic force output and graphics display. The result of haptic interaction is illustrated in the dental training system.
